Mean upper troughing over the PAC NW and western Canada will support general SW flow through the remainder week with weak impulses traversing the flow. Expect mainly dry weather weather as these systems fight very dry low levels, although a few sprinkles may be possible as each weak shortwave traverses the region. Dry air spreading into the region today, scouring out low level clouds and fog. Expect breezy winds with highs in the 50s and 60s. Weak impulse will traverse the region tonight and may support isolated rain or snow showers from northeast WY into NW SD. Mostly virga expected, but a couple showers may reach the ground. Otherwise, for the rest of the week highs will generally be in the 60s, with high temp potentials depending on the timing of the thermal ridges ahead each system. This could allow slightly warmer or cooler numbers than what the current forecast has. Upper trough will lift out the Pac NW early next week, with unsettled looking more likely coupled better chances for precip.
